GridView.PagerTemplate Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the custom content for the pager row in a GridView control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

[TemplateContainerAttribute(typeof(GridViewRow))] 
public virtual ITemplate PagerTemplate { get; set; }
/** @property */
public ITemplate get_PagerTemplate ()

/** @property */
public void set_PagerTemplate (ITemplate value)

public function get PagerTemplate () : ITemplate

public function set PagerTemplate (value : ITemplate)

Property Value

A System.Web.UI.ITemplate that contains the custom content for the pager row. The default value is null, which indicates that this property is not set.

A pager row is displayed in a GridView control when the paging feature is enabled (when the AllowPaging property is set to true). The pager row contains the controls that allow the user to navigate to the different pages in the control. Instead of using the built-in pager row user interface (UI), you can define your own UI by using the PagerTemplate property.

NoteNote

When the PagerTemplate property is set, it overrides the built-in pager row UI.

To specify a custom template for the pager row, first place <PagerTemplate> tags between the opening and closing tags of the GridView control. You can then list the contents of the template between the opening and closing <PagerTemplate> tags. To control the appearance of the pager row, use the PagerStyle property.

Typically, button controls are added to the pager template to perform the paging operations. The GridView control performs a paging operation when a button control with its CommandName property set to "Page" is clicked. The button's CommandArgument property determines the type of paging operation to perform. The following table lists the command argument values supported by the GridView control.

CommandArgument value

Description

"Next"

Navigates to the next page.

"Prev"

Navigates to the previous page.

"First"

Navigates to the first page.

"Last"

Navigates to the last page.

Integer value

Navigates to the specified page number.

The following code example demonstrates how to create a custom pager template that allows the user to navigate through a GridView control using a DropDownList control.


<%@ Page language="C#" %>

<script runat="server">

  void PageDropDownList_SelectedIndexChanged(Object sender, EventArgs e)
  {

    // Retrieve the pager row.
    GridViewRow pagerRow = CustomersGridView.BottomPagerRow;
    
    // Retrieve the PageDropDownList DropDownList from the bottom pager row.
    DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");

    // Set the PageIndex property to display that page selected by the user.
    CustomersGridView.PageIndex = pageList.SelectedIndex;

  }

  void CustomersGridView_DataBound(Object sender, EventArgs e)
  {

    // Retrieve the pager row.
    GridViewRow pagerRow = CustomersGridView.BottomPagerRow;
    
    // Retrieve the DropDownList and Label controls from the row.
    DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
    Label pageLabel = (Label)pagerRow.Cells[0].FindControl("CurrentPageLabel");
        
    if(pageList != null)
    {
        
      // Create the values for the DropDownList control based on 
      // the  total number of pages required to display the data
      // source.
      for(int i=0; i<CustomersGridView.PageCount; i++)
      {
            
        // Create a ListItem object to represent a page.
        int pageNumber = i + 1;
        ListItem item = new ListItem(pageNumber.ToString());         
            
        // If the ListItem object matches the currently selected
        // page, flag the ListItem object as being selected. Because
        // the DropDownList control is recreated each time the pager
        // row gets created, this will persist the selected item in
        // the DropDownList control.   
        if(i==CustomersGridView.PageIndex)
        {
          item.Selected = true;
        }
            
        // Add the ListItem object to the Items collection of the 
        // DropDownList.
        pageList.Items.Add(item);
                
      }
        
    }
        
    if(pageLabel != null)
    {
        
      // Calculate the current page number.
      int currentPage = CustomersGridView.PageIndex + 1;     
        
      // Update the Label control with the current page information.
      pageLabel.Text = "Page " + currentPage.ToString() +
        " of " + CustomersGridView.PageCount.ToString();
        
    }    
    
  }
